Rather than providing cash, ITER's partners have pledged 'in kind' contributions of pieces of the machine. Magnets, instruments and reactor sections will arrive from around the world to be cobbled together at the central site in St-Paul-lès-Durance in southern France. Because no one body holds the purse strings, designs for the machine's components face a tortuous back-and-forth between the central ITER Organization and national 'domestic agencies', which ensure that local companies secure contracts for ITER's components.Managers say the project remains on schedule. But it would hardly be the first time that ITER had been delayed or faced budgetary difficulties."
